GARMENT-FASTENER STUD.

` Specification of Letters Patent,

Patented Dec. 3i, 1918.

Application filed June 15. 1918. Serial No. 240,132.

To all whom z't may concern:

Be it known that I, RAYMOND J. Mo- Bnnnx, a citizen of the United States, residing in the borough of Brooklyn, city of New York, county of Kings, and State of have invented certain new and useful lmproenients in Garment-Fastener Studs, of which the following is a specification.

The object of mv invention is to produce a stud which can be mechanically clamped to goods for use in connection particularly with the socket. set forth iu my companion application Serial No. 240.131, tiled herewith.

In the accompanying drawings forming a part hereof,

Figure l is a diametrie section of said socket attached to goods and detachably connected with the goods-clamping stud forming the present invention.

Figs. Q and 3 are respectively diametrie sections of the goods-clamping and studforming members, separated one from the other.

The drawings show my new stud which comprises two detachable members a and b. Member a comprises a fiat base having a central hollow projecting stud head l, the shank being peripherally reduced at 2 to form an exterior annular seat tor reception of spring members fc carried by the socket y. The ehambered head l is centrally indented forming an axial crosssseetionally round anvil 3 within the chamber of the head. The peripheral reduction at 2 forms the inner wall of the stud head chamber with an upwardly and outwardl flaring annular shoul" .r et which is concentric with the downwardly extending 'anvil 3, an an nular space 5 being left between the opposing walls of the shoulder 4C and of anvil 3, `tor entrance of the iangible tubular projection (i oi. the base of the member This tubular projection is slotted lengthwise at 'to form a plurality of upsettable tongues H for facilitating the flaring or langing ot it when its t'ree end is forcibly squeezed against the anvil which causes the free ends of the tongues 8 to pass tlaringly tlnough the space. 5. The tubular projection is shown passed through goods g, its free end projecting beyond the goods. The exterior diameter of the, projection G is made a sliding fit into the chamber of the shank portion of the stud head. The two members a and L may thusbe mechanically clamped on goods of varying thicknesses, with the stud head and shank projecting for coupling with al socket secured to other goods. The stud head and shank are open on the bottom of the stud base.

lVhat l claim is:

A garment-fastener stud comprising a pair of complementary goods-clamping members one of which comprises a base having a ehambered stud head formed with an' exteriorly reduced shank and open at the bottom ot' the base; the'shank being eX- teriorly peripherally reduced to form a seat and being thereby t'ormed interiorly with. an upwardly and outwardly flaring annular shoulder, and the stud head being provided within the chamber with an axial, cross-sectionally round anvil concentric with and spaced apart Vfrom said shoulder to form an annular passageway between the opposed walls ot the anvil and shoulder; the other member ot the stud comprising a base and a. tubular extension the free end of which is onterable in said passageway and adapted to be flared by compression against the anvil into the chamber above the shoulder.

In testimony whereof I have hereunto set my hand this 12th day of June, 1918. RAYMOND J. MCBREEN.
